Answer
Refer to the graph below.
Work Step by Step
In order to sketch the graph, we should first look at the $(x,y)$ coordinates that satisfy the equation.
We can get some of these points by assigning values to $y$ then solving for the corresponding value of $x$ for each $y$
If $y=-2$, then $x=(-2)^2=4$.
$(4,-2)$ is on the graph.
If $y=-1$, then $x=(-1)^2=1$.
$(1,-1)$ is on the graph.
If $y=0$, then $x=(0)^2=0$.
$(0,0)$ is on the graph.
If $y=1$, then $x=(1)^2=1$.
$(1,1)$ is on the graph.
If $y=2$, then $x=(2)^2=4$.
$(4,2)$ is on the graph.
Plot these points and connect them using a smooth curve to complete the graph,
